Low tire pressure causes rapid and uneven tread wear, impairs vehicle handling, increases fuel consumption, and increases the likelihood of tire failure due to overheating.
Tires with excessively high air pressure impair the smoothness of the vehicle's ride and are more susceptible to damage from impacts with road bumps, potholes, etc. In addition, excessively high air pressure in tires causes uneven tread wear.
It is recommended to visually check the air pressure in your tires every day before driving your car. If you notice that the pressure in your tires has dropped, immediately check the air pressure with a tire pressure gauge.
Check the air pressure in all tires with a tire pressure gauge at least once a month. Even in perfectly serviceable tires, the air pressure can drop by 10-20 kPa per month. Do not forget to check the air pressure in the spare tire at the same time as checking the other wheels.
Air pressure should only be checked on cold tires. Tires are considered cold if at least three hours have passed since the car was stopped or if you have driven no more than 1.6 km after a long period of parking. Inflate the tire or, if necessary, release some air from it to bring the pressure to the standard indicated on the placard attached to the door jamb pillar on the driver's side.
After the car has run for several kilometers, the tires have time to warm up, and the air pressure in them increases by 30-40 kPa compared to the cold state. This is completely normal. Do not reduce the air pressure in warm tires to bring it to the nominal value that is set for cold tires. Otherwise, the tires will be used with reduced air pressure.
You should purchase and have your own tire pressure gauge in your car, which you should use constantly when checking the air pressure in your tires. Keep in mind that tire pressure gauges work with a noticeable error and give a certain spread of readings, so it is preferable to constantly use the same measuring device. In this case, you will be able to notice a tire malfunction in a timely manner: a small decrease in air pressure in a tire can be attributed with great certainty to its damage, and not to differences in the readings of the pressure gauges.
Tubeless tires have a certain ability to restore their air tightness after small punctures. Since air leakage often occurs very slowly, if a gradual decrease in air pressure is detected in the tire, it is necessary to carefully inspect it, paying attention to the presence of foreign objects embedded in the tread.
For convenience, a plate is attached to the driver's door frame pillar, indicating the tire sizes and the standard air pressure in them.
